Then it is desired to reverse the engine the sleeve ii is shifted so ns to engage the levers 'l and 'l with. i reversing enin U2 i'ornied on the sleeve i". the hitter being provided with n shitting eollizfr Y engaged bv n shitting4 lever \YI under the eontrol ot the operator and eonneetcd with the ignition eontroliing deviee It, so as to terrespondingljr ehonge the zit-tunting of the ignition deviees Q nnd Q nt the tiniefthe engine is reversed.

30 L the explosion chamberG into-the openair by When the engine is running and the shaft F is turning in thei direction of the arrow e and the several-parts are in the position illustrated in thedrawings, then the piston C is' near the end of its stroke to the right, havingcoinpressed during this stroke the explosive mixture previously drawn into the compression chamber H. At this time the ports a. and e register with -each other so that the 'compressed explosive mixture can pass from the compression vchamber H into the chest- L and from" the latter by way of the cheek valve N and pipe O into the ignition chamber P" and into the explosion chamber G, int which the charge is ignited as soon or shortly after the crank arm F has reached adead center position, itvbeing understood that the charge in the explosion chamber Gis ignited bythe igniting device Q4 Vhen this takes p ace the iston C is caused to travel from the 'right to t e left, whereby the charge previously drawn into the compression chamber H is compressed while a new charge is drawn into the compression chamber H by way of the passage I, the valve J and supply pipe K. When the piston C is on the return stroke from the right to the left, as abovel mentioned, then the valve S is open-ed by the actionot the cani U on the lever 'l`, so that the products of combustion are forced out of way oi the exhaust port e. ,Ti/'then the piston C reaches nearly the end ot its stroke from the right to the left, then the port b registers with the port d, so that the compressed charge in-` the compression chamber il can pass by way of the said registering ports I) and d, the chest L, pipe O and ignition chamber P into the explosion chamber G, in Wl'iichthe-,com pressed explosive mixt ure is ignited, las soon as the crank arms F have reached or passed the other dead center position so that the piston C vis forced on its torward stroke from the lelt to the right. During this stroke from the lett to the right, the

lprodiuzts of combustion in the explosion chamber G are exhausted by way of the exhaust port f, and the valve S is held open during this period by the action ol the cam U on, the lever 'l` connected with the valve stein S5, previously explained,

y, lt is understood that during the stroke'oi' the piston from the lett to the right, a charge is `drawn into the compression chamber ll 'by ,way of the passage i', the valve J and supply pipe K, to fill the con'lpression .chamber il previous to the return stroke of the piston C tremthe right to the lel't.

-ln order to reverse v4the engine, fhe, operlatm' opens the ('rdinary switchl'i. (see Fig. 2) of' ,the electric current for the electric igniting devices Q, Q', so that thelatter are rendered inactive.

As the engine rs still runmng m the direction of the arrow e, theexi'ilosion chambers a Patent ses/ reo G and G fill with unconsumed explosive mixtures,and when the operator now shifts the reversing lever V to a central position, then the electric current for the controller it is broken, as the said lever V also acts circuit breaker for the controller It, besides shifting the cam sleeve U. When the level' V is in central position. the exhaust valves S, S are' rendered inactive, that is, are held in a closed position, and hence the reciprocating piston C compresses the explosive mixtures in both explosion'.chambers G, G until the pressure in both chambers G, G i: equal and the engine comes to a stop, with the, piston C in an approximately central positionand the crank arms F in an appr .ximately central position.

rlhe switch W' is new closed and the lever V is swung completely over, to close the current tor the controller R and to shift the cam sleeve U to bring the cam U 2 in o )erative engagement with the levers T and 3, so that one of the exhaust valves S or S is opened, that is, .the exhaust valve S is opened if the crank arms F stand upward, and the exhaust valve S is opened in case the crank arms F point downward, The opening of the exhaust valve S or S relieves the corresponding explosion chamber 'G or G of its unconsumed charge, while the chargeI in the other explosion chamber G or G is ignited by the corresponding"igniting device Q or Q, on the operator quickly movingr the lever V .inthe opposite direction, to make contact, for instance, at the opposite side, to set ofi/the corresponding igniting device Q or Q', after which the lever V is immediately returned to proper ruiming position` New when the exploslon occurs in the corresponding explosion chamber G or G', the piston C is moved in the reverse direction, to cause the engine to run in the reverse direction of the arrow a. y

From the foregoing it will be seen that the reversing of the engine is controlled by reversing the exhaust valves and reversingr the controller R for the igniting devices Q and Q.

The engine is provided with the usual packing devices at points where needed, as well as oil cups and other expedients usually employed on explosion-engines.

The cylinders are preferably of the Watereooled type as indicated in the drawings.
